different from that of wrighti. Hammondi is a bird of the woods, both in nesting and foraging, and it stays high up; 25 feet up, in the tract of lodgepoles where today's nest was found, is quite equal to 90 feet up in the high sugar pines and white firs on the ridge up Viola Trail. Hammondi forages about among and through the branchwork of the trees well up, not in chaparral where wrighti is at home. The latter is much the noisier bird, too.

6:50 p.m. - At Hammond Flycatcher's nest again. Stu up the tree - sees young in the nest, he thinks. With string, we find the nest to be 28 ft. 9 in. above the ground (guessed this morning at 25 feet). Stu does the tree work, tying a rope out as far as he can reach, taking a couple of turns on a limb above, and then chopping off the nest limb, which latter is then lowered slowly, the branches below helping to ease the process. In spite of considerable tilting the nest, and four small young it contained, reached the ground without injury. The nest [taken] proved to be 13 feet out from the trunk of the tree. I heard the male call from the treetops in the vicinity, but he did not come to the nest while after
